> a multi-dependency project in the getting started page
That's because they basically don't support monorepo multi-module projects. It's incredibly tedious and makes me long for something like Maven or Gradle (tools that otherwise are often too complicated).
I mean, you can hack something together with local dependencies, yes, but there's no out of the box way to build and test everything together, or to do things like pin dependency versions across projects, have projects inherit shared configuration, etc. We end up creating a bunch of pseudo-projects that contain things like single dependencies, but this blurs the line between build time concerns and actual source code. As with everything in clojure, you can write it all yourself using something like tools.build, but it's not convenient and clearly not a first class use case.
